High Precision Rock Wool Core For Metal Sandwich Panels Thickness Tolerance 0-1mm
Our ultra-precision rock wool is specially engineered for continuous automated sandwich panel production lines. Using high-precision forming technology, it achieves thickness tolerance within 0-1mm with uniform density distribution and no voids or delamination. This exceptional dimensional accuracy ensures uniform pressure distribution during lamination with metal facings, resulting in high panel flatness and elimination of thermal bridging.
Meeting Class A1 non-combustible fire standards with stable thermal performance, it is the preferred core material for premium metal sandwich panels, cold storage panels, and cleanroom panels.
- Continuous automated metal sandwich panel production lines
- Cold storage panels, cold chain building sandwich panels
- Metal sandwich panels for cleanrooms
- Various building facade and roof sandwich panels
- Sandwich panel manufacturing with strict core precision requirements
